I've stayed here twice and you really get a great bang for the buck here. Not only is it super close to the airport, but they also run free shuttles (to the airport and to the subway) and have a complimentary continental breakfast every morning. WIFI is free.
The rooms are quiet, well kept, and comfortable. The staff is super friendly. They do have a lot of deals whether it's via 3rd party companies like Expedia or Hotel.com or whether you sign up for their mailing list or go to their website and pre-pay nonrefundable.
Anyhow, you'll be hard pressed to find an inexpensive decent place near O'Hare Airport. If you have a flight out from O'Hare and you don't want to pay the price for staying in the heart of Chicago, this place fits the bill.
LOVE IT! I plan to stay here again :)
